In interface view, the configuration is effective ononly the current interface.• If no configuration is performed in interface view, the global configuration in MLD view will apply to thatinterface. Configurations performed in interface view take precedence over those performed in MLDview.Configuring basic MLD functionsBefore you configure basic MLD functions, complete the following tasks:• Enable IPv6 forwarding and configure an IPv6 unicast routing protocol so that all devices in thedomain can be interoperable at the network layer.• Configure IPv6 PIM-DM or IPv6 PIM-SM.• Determine the MLD version.• Determine the IPv6 multicast group address and IPv6 multicast source address for static groupmember configuration.• Determine the ACL rule for IPv6 multicast group filtering.• Determine the maximum number of IPv6 multicast groups that an interface can join.Enabling MLDEnable MLD on the interface on which IPv6 multicast group memberships will be created andmaintained.To enable MLD:Step Command Remarks1. Enter system view. system-view N/A2. Enable IPv6 multicast routing. multicast ipv6 routing-enable Disable by default3. Enter interface view. interface interface-typeinterface-number N/A4. Enable MLD. mld enable Disabled by default
